Barn doors, also known as container-style or double-swing doors, are a common rear-closure type for trailers and rigid bodies. They consist of two outward-swinging leaves on hinges and provide a full-width rear opening for loading and unloading.
They can be equipped with either single or double vertical locking bars. Single locking bars offer straightforward and familiar operation, while double locking bars provide more even clamping across the door leaf and can enhance security and sealing performance.
Barn doors are frequently used on box vans, curtainsiders, cargo trailers and ISO containers. When integrated with an appropriate rear frame, they are compatible with EN 12642-XL rated bodywork and can support demanding load-restraint requirements.
For operations where rear appearance and branding are a priority, barn doors can be supplied as flush-fit designs, providing a smoother external surface that helps create a clean livery layout.
FAQs
What are barn doors?
Barn doors are a rear-closure system made up of two outward-swinging hinged leaves. They are widely used on trailers and rigid bodies where a full-width rear opening is needed for loading and unloading.
What is the difference between single and double locking bars?
Both systems use vertical locking bars to secure the doors. Single locking bars typically use one bar per leaf, while double locking bars use two, helping distribute clamping forces more evenly and improving overall sealing and security.
When would you choose single locking bar barn doors?
Single locking bar doors suit operations that prioritise simple manual handling and familiar operation. They are common in general haulage and multi-drop work where quick door access is important.
When would you choose double locking bar barn doors?
Double locking bar doors are chosen for higher body heights or when enhanced rigidity, sealing performance and security are required. They help maintain tight closure across the door leaf, especially on EN 12642-XL rated bodies.
Are barn doors suitable for EN 12642-XL rated bodies?
Yes. When paired with an appropriate rear frame and body structure, barn doors can form part of an EN 12642-XL compliant solution, supporting load containment and structural integrity.
Can barn doors be supplied as flush-fit doors?
Yes. Flush-fit barn doors are available where a smoother external surface is preferred. They can improve the visual appearance of rear livery and branding.
How do barn doors compare with roller shutter doors?
Barn doors generally have fewer mechanical components and may require less maintenance than roller shutters. Shutters can be advantageous in confined loading bays, while barn doors provide a full-width aperture and a simple, robust closure method.
